Description

Band defecator transfusion device

Technical field

This utility model relates to a kind of improvement of transfusion device, specifically a kind of band defecator transfusion device.

Background technology

The transfusion device that in transfusion, uses at present, comprise that particle size syringe needle, breather, tube for transfusion, Mo Feishi dropper, control valve, injection needle constitute, though the existing extensive use of this transfusion device, but also there is the some shortcomings part: the one, small items in the atmosphere and infection bacterium, be easy to enter in the infusion bottle by air inlet pipe, dissolve in the medicinal liquid, cause the cross infection in the infusion process; The 2nd, infusion bottle makes up a prescription, changes pin and pulls up, and easily impurity such as plug microgranule is brought in the infusion bottle, splashes in the blood of human body with medicinal liquid, brings harmful effect for transfusion person.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and strainability is strong, avoids small items, impurity, infection bacterium etc., enters in the blood of human body with medicinal liquid, improves the band defecator transfusion device of injection quality.

For reaching above purpose, technical solution adopted in the utility model is: this band defecator transfusion device, constitute by particle size syringe needle, breather, tube for transfusion, Mo Feishi dropper, control valve, injection needle, it is characterized in that establishing defecator on the tube for transfusion below the Mo Feishi dropper.This utility model is also implemented by following measure: described defecator, by net shell, rack, silk cloth drainage screen, advance the medicinal liquid mouth, go into the medicinal liquid mouth, go out the medicinal liquid mouth, the net cap constitutes, net shell one end is established external screw thread and is connected with the female thread of net cap, establish rack in the net cap, on rack, establish into the medicinal liquid mouth, silk cloth drainage screen is wrapped on the rack, is establishing into the medicinal liquid mouth on the net shell upper end wall and on the net cap respectively and is going out the medicinal liquid mouth, and be communicated with tube for transfusion is upper and lower.When using this utility model, in infusion process, medicinal liquid enters in the net shell by advancing the medicinal liquid mouth, organizine silk drainage screen is trapped in small items, impurity on the silk cloth drainage screen, filtered liquid medicine is by going into the medicinal liquid mouth on the rack, enter in the rack, medicinal liquid enters in the tube for transfusion through going out the medicinal liquid mouth again, reaches the purpose that improves injection quality.

The beneficial effects of the utility model are: compare with present transfusion device, have simple in structurely, strainability is strong, improves the advantage of injection quality.
